Voltage Sensorless Synchronization of a Grid-Side Converter Based on a Discontinuous Operating Mode and a Sliding Mode Observer

Recent advances in the control of grid-side converters (GSCs) aim to improve system reliability by eliminating the need for voltage sensors. Effective control without voltage sensors requires both synchronization before the GSC is connected to the grid and continuous operation afterwards. To meet th...
